Recall Notice

AllTerrainBum · November 1, 2015

I received a recall notice in the mail the other day that may or may not affect my truck (2015 Denali 2500HD, Duramax). The recall has something to do with a diesel leak near the exhaust system. I went to look under the truck today and found this: (passenger side near the front of the transmission)

I don't think it's exactly what the recall is concerned with. This looks more like a transmission seal leak. Anyone else see this before and if so, what was involved in fixing it? I'll of course contact my dealership on Monday and get it scheduled to have it taken in.

I just stopped by the dealership. I showed them the pictures, and they've scheduled to take a look on Thursday. I asked if he'd seen this before, and said that it may be a rear main seal. They've replaced two of them so far on this model.

Anyone know what's involved in repairing a rear main seal on this? Sucks that it only has 5k miles...

My previous 07 Vmax had 2 rear main seals replaced. I was told it was an issue with the trucks of that model and they've done several. The only reason it was done twice was because the tech didn't do it right the first time and caused it to leak again. At the time, the dealership took full responsibility for the second repair but would have anyways based on mileage.

The recall is for the leaking down pipe connection. You would know if you had this issue due to smoke rolling out of the fender well and people hollering that your truck is on fire. Been there. It could be the rear main seal but more than likely it is an oil gallery plug in the bell housing, has been an ongoing issue since 2011 from my reading.

Just got the truck back from the dealership. They said it was the seal on the lower oil pan. They took it off, resealed it, let it cure then tested it. They said I should be good to go. They also went ahead and did another recall (something about a lower plug) and changed the oil, since I was at 5k. Hopefully this will take care of the issue. I'll be keeping an eye on it to make sure.

Good deal, glad they got you fixed up.
